Abstract

A stay vane ring for the spiral casing of a rotary hydraulic machine comprises two axially spaced-apart ring members disposed coaxially about the machine axis and a plurality of axially extending stay vanes connected between the ring members. Each ring member comprises a substantially cylindrical ring of metal plate and the axial ends of the stay vane plates are extended in axial direction on both sides of said cylindrical plate ring of the ring members at least substantially all the way out to the most distant circular edge of the cylindrical plate ring so that a cross-joint is formed between each stay vane plate and the cylindrical plate ring of each ring member. At each such cross-joint the stay vane plate and the cylindrical plate ring are welded to each other.
